Curve Fitting | PSpice

One of the challenges faced by circuit designers is optimizing multiple simulation models or circuit parameters to match the behavior of an actual device or circuit behavior described datasheets. The curve-fitting capability in PSpice Advanced Analysis Optimizer provides an effective method of optimizing circuit and device parameters such that the simulation output matches a pre-defined goal represented in the form of a curve or an x-y table. Curve-fitting can be used in cases where performance is best described as a waveform or is not measurable in terms of a function or a value, such as in wave shaping circuits.
